PLATE-PRINTING MACHINE.

Application filed November 3, 1923. Serial No. 672,507.

To @ZZ whom t may concer/1t.'

j Be it known that l, Rnnonrr Sir'rnnn, a citizen ot' the United States, residing at Cincinnati, in the county of Hamilton and State ot Ohio, have invented certain new and useful improvements in Plate-Printing Machines, or' which the following is a specification.

My invention relates to printing trom engraved plates, and more particularly to Inachines such as those disclosed and claimed in my Patents, No. 1,447 ,433, 'dated March 6, 1923, No. 1,447,434, dated March 6, 1923, and 1,447,435, dated March 6, 1923, and No. 1,497,304, dated .lune 10, 1924, on which my present invention is an improvement. In many respects, the present machine is the same as the one specifically claimed in the two last mentioned patents; and these two patents will be referred to herein in connection with the description ot several oi" the details, and also are reierred to as to broader claims therein for several parts ot the present machine. rllhe object ot the present invention is to :turther increase the ease and accuracy oit operation, and to provide greater strength and durability, as well as t make the machine more sate and convenient for the operator. Other objects will appear in the course ot the ensuing description.

lf attain these objects by the device illustra-ted, for example, in the accompanying` drawings, in which- Figure 1 is a plan view, certain parts being broken away to reveal underlying details;

Fig. 6 is a detail trent elevation of the manipulating means .tor the controller engagingl mechanism lFig. 7 an enlarged detail sectional View ot the arch-cap clamping means.

The frame comprisestlie base 1, sides 2 and 3, and strut ot Hshaped cross-section', the latter rigidly connecting they sides 2 and 3 together about midway ot their Vlength and height. rlhe bed slides in guideways in the upper parts of the sides 2 and 3, rearwardly and forwardly, rand is supported by rollers 6, 7 and 8, with straight lower races 9 on these rollers'. rlhe pressure roller 10 bears continuously from end to end up against the continuous lower bearing side ot' the front part 11 of the bed 5 when the latter is in rear position as in Fig. 5, vaffording a firm support during the actual printing operation.

Each trame side 2 or 3 has on its top rear pedestals 12 and front pedestals 13; and the arch-caps 14 have rear legs straddling the rear pedestals 12 with transverse pivots 15 therein, and have their front ends over the front pedestals 13, trom which tension rods 16 extend up through openings in these front end garts, these rods being threaded in their upper end parts (Fig. 7). The cup-shaped nuts 17 have their bottoms threaded on these rods 16 and receive loosely in their open tops the tubular lock-nuts 18 also threaded onto the rods 16. `The nuts 17 and lock-nuts 18 have transverse holes in their walls, which register, receiving pins 19 to lock the two together at various adjustments up and down on the threads of the rods 16; the two nuts 17 and 18 compressing between them a spring 2O coiled around the rod 16 against the bottom of the cup of the nut 17 and the lower end of the locl-nut 18. rlhev casing 21 surrounds the nut 17 and may be clamped'to turn the nut 17 by a set screw, 22; the casing having wings 23 alfording tii'iger-holds for screw ing the entire device up or down on its respective rod 16.

Each arch-cap 14 is channeled on its lower side, receiving the ball-bearino' 24 support-ed on top of a compression spring 24 which allows the arch-cap and bearing 24 to be adjusted up and down by the nut 17 yet always holds the bearing firmly. The spring binds the two nuts 17 and 18 on the threads of the rod 16, so that, once adjusted, the bearings 24 will be held firmly. The segmental f-roller 25 is Fixed on the transverse shaft 26 journaled in thev balllbearings 24 ofthe respective arclrcapsf, to rotate over the bed and this shaft 26l extends` to the lett hasy tiredk enit-a spurgear'27 meshing with alarger spur gear 28 turning'on a stud in the frame side Z and meshing with a third spur gear 29 similarly mounted and being of the same diameter as the first gear 27 and having coaxial and turning with it the pinion 30 meshing with a spur gear 3l which is of four times the diameter of this pinion 3() and tnrnson a stud extending in to the right from the inner wall of a housing 32 (shown only by dotted lines in Fig. 3) Vbolted to the side 2 down at the rear of the machine.

The cam-disk 33 is fixed on the left outer end of t-he main shaft 34, facing the inner side of the large gear 3l and carrying the cam element 35 to coact with any one of four engaging bars 36 fixed on lugs projecting in from the gear 3l, at equal intervals tlierearound. The axis of the cam disk 33 and shaft 34: is parallel with that of the gear 3l that has these bars 36, but lies a substantial distance thereabove. The cam element 35 has the shape of a segment at each end; the segmental radius at one end, however, being much smaller than the other, and the curves of the two being joined by a straight surface, while the opposite edge of the element is straight.. This element is set on the disk 33 with its larger end radially inward and having the point 37 thereof on the axis of the disk. The bars 36 are so set on the large gear 3l that their inner corners 38 will coincide with the disk axis in passing around with the gear 3l; and these bars are so uniformly inclined to the circle of rotation, and the cam element 35 is so inclined and of such length, that, beginning with the inner point of this member coincident with the inner corner of one of the bars 36 and the cam element 35 inclining down to the front, a rotation of the disk 33 one complete revolution over rearwardly will cause onefourth of a revolution 'of the gear 3l over rearwardly; the engagement terminating as the point of the smaller outer end of the cam element 35 slides oli' the inner corner of the bar 3G after the entire edge, formed by the curves and straight junction part before described, has traversed in engagement with the straight face of the har 36.

The main shaft 3st has hearings 39, inside of and on the base l of the frame: and a casing LlO is mounted between these bearings, enclosing a worm gear il fixed on the shaft and meshing with a worm 42 therebelow, also enclosed in the casing et() and fixed on the driving shaft 43 journaled from fron't to rear of the machine in bearings in this casing l0 and in the front and rear ends of the base. l. This shaft 43 extends out at the rear, and the driving pulley A turns loosely thereonv and has inside its rim, to the rear, the cone shaped surfaee 45 to receive the conical periphery of the clutch member d6, preferably of wood` fixed on a rotor 417 mounted on the shaft 3 by means of a spline 48 Fig. 3) and carrying, spaced back from it, an engaging disk 49 keyed on the hub of the rotor. The rear end part of the shaft i-3 is threaded, receiving the cup shaped nut 50 which encloses a spring 5l coiled around the shaft 43 and compressed by this nut 50 against the rear end 0f the hub of the rotor 17; the nut 50 being locked by a lock-nut 52 against its rear end.

The base 1 of the frame has an extension at the left of its rear end, carrying the fulcrum for a fork 53 extending to the rightand straddling the hub of the rotor 47, with bearing blocks 54k against the front face of the engaging disk a9, above and below the hub. The push-rod 55 extends from front to rear of the machine, sliding` and rotating in bearings 5G and 57 in the front and rear ends, respectively, of the base l and having its rear end part loosely threaded into the right hand end of the fork 53 l) by means of a sleeve 58 locked to the fork by a nut 59, for adjustment forwardly or rearwardly in the fork. At the front end of the machine, an arm 60 is fixed on this push-rod 55 with its upper end pivoted to a connector 61 inclining up to the left (Fig. (i) and pivoted in the fork G2 of a manipulating lever 63 fulcrumed on the front of the frame and extending up to the left and terminating in a knob Gli. The connector 61 extends to the left past the fork 62 to engage with a lug 65 on top of the lever 63 as the lever is pushed up by a spring` GG coiled around a rod 67 having its lower right end pivoted on a stud in the frame aud its left end through a downwardly extending lug 68 on the lever 63` with the spring 6G compressed between this lug 68 and the pivoting head of this rod S7. A shaft 69 is journaled transversely in the right hand side of the base l, with a handle bar 70 extending down and forward from its outer end, and haring its inner end next to the push rod with one side provided with a recess 71; and a collar 72 is fixed on the push rod 55 just rearwardly from this recessedy end. in such position that. if the shaft (39 is turned so that its recess 7i faces this collar 72, the rod 55 may slide forwardly` but otherwise the unrecessed part of the shaft G9 will engage this collar and prevent forward nuirement of the push rod The main shaft 34 carries on its inner right end the crank 73 with a roller against the front side of a longitudinal flange on the main lever 75 which has its fulcrum 7 G in a lug extending down from the base l, which base is slotted to allow movement of this lever. The bed 5 has depending ears 77 to the rear of the pressure roller l0, between which is pivot-ed a link 7 3 inclining down, when the bed is forward, to pivot to the upper end of the main lever 75; this arrangement being such as dislll medias closed and claimed in niy prior Patent No. 1,447,435 before mentioned, and the roller 74, by which the crank 73 swings the lever backward but can not swing the lever forward, is such as disclosed and claimed in n'iy prior Patent No. 1,49*?,30-1, before inentioned.

The throw-out lever 79 has its fuloruin 80 in the right hand side of the base 1 and e1;- tends to the left, with an openingthrough which the push rod entends, and the left end of this lever 7 9 is engaged by the lower end of the rocking lever 31 fulcruined at 82' on a block 83 mounted on the bottoni of the base 1; this block alsoholding an additional bearing for` the push rod rthe upper rear face of this rocking lever 81 is rounded, and is engaged by the edge of a cam plate 81 fixed on the lnain shaft 34 to the leftV of and coincident with the crank 73, so that as this cani plate 84 swings up forn wardly, it pushes the upper end of the rocking lever 31 forward and the lower end thereof backward, Aand thus swings the throw-'out lever 79 backward. A iiange 85 has `a hub around the push rod 55 at the rear of the throw-out lever 79, having a set screw clamping this flange to the rod 55; and the front face of this flange has a recess 86. A roller 87 is iournaled on the rear side ofthe throw-out lever 79 to bear against this front face of this flange 85; the parts being soadjusted that when the push rod is rocked over to the left by depressing the manipulating lever 63, the recess S6 registers with the roller 3T, allowing the push rod to slide forward, although the throw-out lever is held back by the engagenient of the cani plate Set with the rocking lever 81.

For returning the bed 5 forwardly, a web 38 has its end lined `to the rear end of the bed at the right, inside the traine, and passes forwardly, downwardly and to the rear, around a sinall sli'eave 89 jornnaled on the saine stud with the forvard one 7 of the two rear bed-supporting rollers at that side, and then over another siniilar shcave 90 jourualed on a stud in the rear end of the 'traine side 3. Frou: here the web 88 passes vertically downward along a guide 91 eX- tending up from the rear end ofthe base .l (Fig. and has its lower ond fixed in an eye ou the upper end of the weight rod 92 that passes down through and is guided by a foot 93 on the lower end of this guide 91. rlhe lower end of this rod 9:3 carries a weight 94- wi-th a recess in its 'top around the rod 92 receiving the lower end of the spring 95 coiled around the rod and compressed against the bottoni of the foot 93 as the weight is pulled up when the bed is approaching rearinost position as seen in Fig. 5.

To cushion the front end of the bed travel,

a yoke 90, mounted across the rear end yof the traine top with its end parts forming clips to hold the bed down in its guides, has

fornied in the top of its iniddle a horizontal rearwardly opening dash-pot 97; and the `Ncar its front end the dash-,pot 97 has a port 101 controlled by a sin'all check-'valve 102 which admits air niore freely than it allows the air to escape; thus avoiding obstruction in rearward starting, but causing sonie conilpression of air as the plunger enters at ending of the forward stroke. rlhe 'slight vaeuuin created at beginning of backward travel preifents too sudden starting andl jai"- rin'g of the stock frein its position o'n the bed; thus contributing to this result along with the arrangement of niain'lever 75 and link 78 as fully described and claimed in niy prior Patent No. 1,4%?,4355 this dash-pot arrangement also being fully disclosed and claimed in ray prior Patent No. 1,497,304, before mentioned.

rThe gearing which transmits the nio'tion frein the n'iain shaft 34 to the lll-roller 25 of course has back-lash; and as the crank T3 can drive the bed 5 backward, but could not prevent inanual pushing` of the bed backward, a. detent is desirable to vprevent this, as for instance, should the operator lean against the front end of the bed. To` aiilord a positively positioned stop for the D-roller 25r in its raised inoperative position, a cani 103 is fixed on ,the shaft 2G at the right hand end of the D-roller 25, with an iiicrease in its radius terminating in an abruptndrop 104', and a second drop 105. The detent ,housing 105 is pivoted on an inward exten` sion of the pivot 15 of the adjacent archcap 1st, with an arni 10'? inclined upward and forwardly, having a roller 10S to bear on the periphery of the cani 103 and lit in the lirst drop 104 thereof when the lll-roller is in its inoperative position. This housing 106 is open at its bottoni, and a dog 109 is hung on the pivot 15 and pressed down past the bottoni of the housing by a sniall spring 110 between it and the top of the housing. The edge part of the bed 5'has on top a lug` 111 with gently inclined front and undercut rear end; and the dog 109 has a nose 119J on its rear end with front sloped upA rearwardly to wedge down under the rear end of the bed lug 111 if the bed starts backward, The front edge of the bottornof the housing 10G engages under the dog 109; and as the D-roller 25 ystarts over forwardly, the roller 108 drops into the second drop 105 of the cani 103, upon which the housing 10G is swung up by a spring 113 around the pivot with one end engaged in the housing and the other in the pedestal 12; the dog 109 being raised with the housing, out of the path of the bed lug 111. This is permitted because the bed 5 starts much more slowly than does the D-roller; the dog 109 being set with some clearance from the bed lug 111 to take advantage of this differential, but being close enough to prevent any material backward travel of the bed under the circumstances described. During forward return travel of the bed 5, the dog 109 rides up the front side of the bed lug 111 and drops behind it automatically under action of its spring 110, although the roller 103 has not yet been reached by the second drop 105.

Further to insure a stationary condition of the D-roller before starting, a second cam 114 is fixed on the shaft 26 to the right of the cam 103, with a recess 115 in the otherwise circular periphery. A rocker yoke 116 has a fulcrum 117 on to of the archcap 14 and its front end carries a roller 118 down against the periphery of this cam 114, while its rear end carries a small barrel over the rear part of the arch-cap 14, enclosing a small spring 119 between an adjusting screw 120 in the upper end of the barrel and a small plunger 121 projecting from the lower end thereof down against the top of the arch-cap 14, so that the spring yieldingly holds the roller against the cam, to enter the recess 115 when the D-roller reaches correct stopping position. Also, to prevent undue momentum of the D-roller, in stopping or in the initial stages of starting, a brake shoe 122 bears on the periphery of this cam 114 at the rear, and is mounted on the lower front end of a plunger 123 in the end of a barrel 124 forming part of the arch-cap 14 and having an adjusting screw 125 in its upper rear end, compressing a small spring 126 against the plunger' 123.

Between the left end of the D-roller and the adjacent arch-cap 14, a third cam 127 is fixed on the shaft 26, for operating a guard comprising a bar 123 which extends across between the bed and the D-roller from the lower end of a lever 129 having its fulcrum 130 on top of the arch-cap 14 and curving back under the shaft 26 at the right of the cam 127. This lever 129 has a roller 131 bearing on the cam periphery, about half of which periphery is coaxial with the shaft 26, and the other half receding rapidly radially inwardly from the bottom (when the D- roller is up) to the top, where is abruptly curves outward, forming a rest for the roller 131 in stationary condition, during which the guard bar 123 is back under the D-roller. As the latter starts over forward, the abrupt outward curve of the cam periphery pushes the roller 131 upward, quickly carrying the guard bar 12S forward and upward, out past the circle of travel of the descending larger operating part of the D-roller, and forcing the hand of the operator away therefrom if not removed in time by the operator. As the D-roller returns to inoperative position, after operating, the roller 131 rides along the receding part of the cam 127, so that the guard bar swings back under the D- roller, under the action of a spring 132 coiled around the fulcrum of the lever 129, which turns in a bearing on the arch-cap 14; this spring having one end fixed in the archcap and the other end in a small cylindrical housing 133 fixed to the fulcrum and enclosing the spring, as seen in Fig. 1.

It will be understood that, in use, the gearing would be covered by a suitable guard. not shown; and that the machine would be mounted on a suitable stand. such as disclosed in the patents mentioned, with a motor thereon, below, at the rear, belted to the pulley 44; this motor operating continuously, but the machine being operated only when the clutch member 46 is engaged therewith under action of the spring 51. The pressure roller 10 is journaled in blocks 134 slidable up and down in slots in the frame sides 2 and 3, as adjusted by screws 135 eX- tending up through projections on the outside of the frame, with heads and lock-nuts 136 below these projections (Fig. 5.) The usual bracket 137 under the bed 5 at the front, for holding a heater for the ink placed on the plate on top of the bed, is similar to that of the prior patents mentioned; and the bed has the tray 133 at its front end, for convenience of the operator, as in the prior Patent No. 1,497,304.

In operating the machine, after the plate has been suitably fixed on the bed and inked and the stock placed thereon as correctly located by a line drawn on the plate, and held m position only by its friction with the plate, as usual in j )late-printing. while the bed 5 is at the front and the D-roller raised, as shown in Figs. 1 to 4, inclusive, the manipulating lever 63 is depressed by the operator engaging the knob 64 thereof. The cam plate 84 is holding the throw-out lever 79 back, which, engaging its roller with the flange is holding the clutch member 46 away from the pulley 44; but this action of the operator rocks the push rod so that the recess 36 registers with the roller 37, allowing this push rod 55 to slide forward. and with it the clutch member 46 into firm frictional contact with the rotating pulley 44, thus starting the driving` shaft 43, which. through the worm 42 and worm gear 41, rotates the main shaft 34 over backwardly, swinging the main lever by engagement of the roller 74 of the crank 73 therewith, and very slowly and gradually starting the bed 5 backward as the link 78 assumes a greater' angle to the lever 75 and as the crank 3 reduces its angle to this lever; the suction in the dash-pot 97 tending to retard the starting, as betore alluded to. y i

,el thek saine time, theV cani element starting` overv backwardly with the main shaft 23st troni the position best seen in Figs. 3 and has its point 37 beginning to engage the uppermost one of the er y `ging bars, 30 on the gear 31; at which stage, lbeing substantially central of the shalt 34, the driving action on the gear 81 is almost nil; but as the rotation continues, parts of the caniI elenient 235 farther ironi'the center of the shaft le bear on the bar 3,0, which, having a greater lineal velocity, drive the gear 81 with gradually inpreasing speed. rlhe design oft this cani elenient 3,5 is'such that, LS the gear 31 transmits its gradually increasing velocity to Vthe D-roller 25, the latter will have its surface inoving at the saine velocity as the upper surface of the stock when the D-roller has rotated over andidownward andthe stock has been carried, with the plate and bed, backward under the D-roller. Itwillb'e understood that this D-roller, as fully set Jforth in the prior patents, andas is well ltno wn in the art, vis covered with a suitable blanlfet or backing, held by Asuitable clainps 'l-s) (Fig. 3) which contacts with the stock; and it is with respect to the radius of this covering that the parts are designed, so that at the instant ot' contact with the stock, this covering is inoving at the saine speed as the stock, avoiding slippage of the stock on the plate.

As soon as the operator reinoved the hand frni the manipulating lever 63, the spring (3lrocked the push rod 5,5 over to ther right again, until the connector G1 engaged the hir; ot the lever 63; but during the time,

Vt' this action, which is slow relative to that o l: the niachine driving device, the caniplate h--- has lett the rocking lever 81 so that there is nothing to niovc the throw-out lever Z0 bimliward, and the clutch member 4G will remain in Contact with the pulley 44.

The printing operation then progresses, with the bed 5 traveling backward and the lil-roller rotating under and upward to the rear until the parts are in the positions shown in Fig. 5 with the crank 73 at right angles to the lever 5 'and ready to recede therelroni as it continues to rotate under and torwardly. The het 5 has pulled the weight 011- up until the latter has compressed the spring as seen in Fig. 5, cushioning the travel ot the bed so that- 'the latter stops at this point, having gradually becon'ie slower by the crank and lever action, without jar. Now, the weight 9st will pull the bed 5 forward, independently of the action ot' the main lever '75, until stopped gradually'by the dash-pot 9T as betore describedv- As seen in 5, the cani eleinent 35 still and 11S in the caniy parts 104, 115, the lil-roller` is stopped without ar, ,accuratelyl in its lcorrectI position for starting again at Athe next printing operation. In soine cases, the lirst drop 10-l of the cani 103 inay be omitted, using this cam 103 only for operating the i i i dog 109 as betere described, and depei'iding upon the roller 118 in the recess of the cani 11ito insure the correct stopping of the D-roller. yThis especially is permissible in conjunction' with the brake device 122 which overcomes any tendency of the D-rollery to continue backward and overcome the action ol the stopping roller 118 alone.

At the next operation, since the gear 31 rotates only one-tourthturn to one ot the D-roller, and the engagement! of the cani eleinent and bar 3G is such as to provide exactly this one-fourth revolution of the gear 31, the point A37, centrally of the driving shaft 34,`will be at vthe inner corner of the next bar BGotthe gea-r 31, over ytorwardly.; the close approach ofA this point 3'? to this cornerbeing yseen in Fig. 5. Ilhese parts thusl are in positions to cause the very gradual starting of thefD-roller again at this nent operation The Vcani plate 8,4, at ending of the coniplete revolution ot' the shaft Biland 'crank 73, engages the rocking'lever 81, swinging the throw-out lever y70 backward, and, as the recess 8G was rocked away from the roller S7 as soon as ther operator released the nianipulating lever (i3, this throw-out lever pushes the push rod backward, which pushes the clutch nieinber of away from the pulley 4&1, disconnecting the motor troni the. machine. n

` Ifiit is desired to prevent operation ,ol the inachine, as while the operator is making `adjustments'ofthe plate4 or' the D-roller covering while the inotor ils'running, or as when leaving the machine unattended without stopping the motor, the handle bar is swungr up forwardly, bringing the unrecessed part ot the shaft 69 againstthe collar 72. This device is in convenient reach of the ope ator, who may use it at any tiinc, and may throw it off to permit starting, with ease. It is especiallyv useful where, as is the practice, the skilled operator inks the plate and supervises the operation of the machine, and less skilled helper places the stock on Vthe plate ready for accurate setting bythe printer, and then depresses the 1naiiipulating lever 63 for the printer as soon as the latter is ready for the machine to be started. rl`hus, the printer may protect the work against mistaken action of theV helper at any time the situation seems to demand suoli precaution. lith the'bar T0 downward the lever 63 can be depressed, but no further action can occur.

The casing 21 is removed from the nut 17 if it is desired to change the pressure of the binding spring 20; this permitting the pin 19 to be removed endwise and the lock-nut 18 screwed up or down; the holes in the walls of the latter being elongated up and down to permit this, and the adjustment or course always being suoli that the holes in thet-uo nuts 1T and 1S register, and amounting, therefore, to one or more halt revolutions ot the nutv18 relatively to the nut nrlhe various details ot the invention have been somewhat specifically described, to malte clear the construction and use thereof, as is required, but l do not wish to bel understood as being limited to such precise 'showing and description, but having thus fully described my invention', what I claim as new and desire to Ysecure by Letters Patent is:
